Tris(2-methyl-8-quinolinolato)iron(III) was proposed as a sensitive spectrophotometric silanol-detecting probe based on the coordination ability of silanol groups on the surface of octadecylsylanized silica gel (ODS silica gel) for reversed-phase high-performance liquid chromatography. A peak of the iron(III) complex on a chromatogram abruptly collapsed as the silanol content in an ODS column increased, indicating that the iron(III) complex could sense trace amounts of silanol groups.

Tris(2-methyl-8-quinolinolato)gallium(III) as a fluorescent probe for sensitive silanol-testing.
The peak height was the most effective parameter among the peak parameters, and much more sensitive than the silanol-detecting tests using nitrogen-containing compounds, in detecting a trace amount of silanol groups that could not be detected by other sil ethanol-detection tests.
